There are described bis(resorcinyl)triazines of the formula ##STR1## The compounds according to the invention are particularly suitable as sunscreens in cosmetic, pharmaceutical and veterinary medicinal preparations.

Bis(resorcinyl)triazines useful as sunscreens in cosmetic preparations

A synthetic aromatic polyamide fiber containing an ultravoilet light screener in a form such that any agglomerate thereof is less than 0.01 micron in diameter is obtained by imbiding a dispersion or solution of the screener into aromatic polyamide fibers that have never been allowed to become dry after being spun.

Method of impregnating polymethyl methacrylate

Heat resistant aminium salt infrared absorbers

Compositions containing an organic material normally subject to oxidative deterioration and a hindered phenol metal phosphonate, such as nickel bis((O-n-butyl-3,5-di-t-butyl-4hydroxybenzyl)phosphonate), an ultraviolet light absorber such as a benzophenone or a benzotriazole and a light stabilizer such as a p-hydroxybenzoate. Such compositions are stabilized against oxidative, thermal and light deterioration.
